Abstract
Rubrivivax benzoatilyticus JA2 produces indoles with simultaneous utilization of Ltryptophan Fifteen chromatographically distinct indole derivatives were detected from the Ltryptophansupplemented cultures of R benzoatilyticus JA2 Nine of these were identified as indole 3acetamide Methoxyindole3aldehyde indole 3aldehyde methoxyindole3acetic acid indole 3acetic acid indole3carboxylic acid indole3acetonitrile indole and trisindoline Tryptophan stable isotope feeding confirmed the indoles produced are from the supplemented Ltryptophan Indole 3acetic acid is one of the major products of Ltryptophan catabolism by R benzoatilyticus JA2 and its production was influenced by growth conditions Identification of indole 3acetamide and tryptophan monooxygenase activity suggests indole 3acetamide routed IAA biosynthesis in R benzoatilyticus JA2 The study also indicated the possible multiple pathways of IAA biosynthesis in R benzoatilyticus JA2
